Make a perfect 1:8 scale replica of a western saddle.
Strap it on the back of your cat.
Stand outside your house, holding the reins, until someone asks the inevitable question,
"Surely, you don't think you can ride that animal, do you?",
at which point you squint up at the sun, spit some tobacco juice on the ground, and laconically reply,
"'Course not, pardner, he's way too high-spirited."
